Incorporating Nature-based Stormwater Strategies early into the design phase of new projects yields the most effective application of its use.

Nature-based Stormwater Strategies such as permeable pavement, cisterns and rain gardens promote infiltration and rainwater reuse. These techniques reduce stormwater runoff even on high density development sites.

We saved about $2 million in development costs on 100 lots by not installing curbing and by using natural areas as infiltration basins and not having to excavate for wet ponds.
